Variation on the Shielded-Loop AM Antenna Mar 25, 2002 12:00 PM Greg Manfroi of WIUM/WIUW, Western Illinois University, Macomb, IL, sent us this idea on a construction method for the shielded-loop AM ...

This 4-part report discusses antenna fundamentals and the various types of antennas used for short range devices. Fundamentals are presented along with practical design principals. It is excerpted ...

A smaller antenna is no less the challenge when it comes to designing one that can be carried though, and [Thomas Witherspoon] demonstrates this with a foldable loop antenna for the 2 metre band.
